Darrick J. Wong 0df5c39b3e xfs: bump INUMBERS cursor correctly in xfs_inumbers_walk
There's a subtle unit conversion error when we increment the INUMBERS
cursor at the end of xfs_inumbers_walk.  If there's an inode chunk at
the very end of the AG /and/ the AG size is a perfect power of two, the
startino of that last chunk (which is in units of AG inodes) will be 63
less than (1 << agino_log).  If we add XFS_INODES_PER_CHUNK to the
startino, we end up with a startino that's larger than (1 << agino_log)
and when we convert that back to fs inode units we'll rip off that upper
bit and wind up back at the start of the AG.

Fix this by converting to units of fs inodes before adding
XFS_INODES_PER_CHUNK so that we'll harmlessly end up pointing to the
next AG.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
